When preparing lessons, teachers should not only prepare knowledge points and ordinary teaching links, but also pay attention to students and diversified classroom teaching effects, not just exams.

Think about what teachers should do, how students should learn, and regard students as supporting roles. At the same time, it is necessary to design a teaching plan around what problems students have and what reactions students need, and contact students' current level and learning ability to dig out the combination point and breakthrough point of imparting various knowledge, cultivating ability and mental health education. Doing this is equivalent to laying a solid and feasible foundation for "the infiltration of mental health education in mathematics teaching". So how to dig the breakthrough point of mathematics teaching and mental health education? Mental health education is actually an education contained in life, which is closely related to all aspects of life. Therefore, as long as we fully understand the content of mental health education, carefully study the teaching materials with new eyes and ideas, and combine students' own characteristics and psychological problems, we can dig out valuable mental health education content from mathematics teaching. For example, when we teach the relationship between total workload, time and efficiency, we can contact the problem of laziness among students, choose the calculation examples of the total amount, time and efficiency of students' own homework every day, and add the calculation of the total amount, time and efficiency of different people's daily work. While completing the teaching task, we can educate students on mental health to cherish time and change procrastination.

Second, the classroom is the main position of mathematics teaching, and infiltrating mental health education into students through the classroom is the main way to achieve the goal.

In mathematics classroom, the formulation and implementation of each teaching step should be adapted to students' psychological level, and the teaching should be carried out according to the track of students' cognitive development level, which just meets the requirements of mental health education-students gain knowledge and ability, at the same time, their psychological quality has also been exercised, and their original psychological cognitive level has also been improved, thus achieving a good educational effect of "moistening things and being silent".

(A) to enhance students' sense of national pride.

Mathematics textbooks contain abundant materials on the history of mathematics, which can not only help students to establish national self-esteem and self-confidence, but also stimulate students' strong patriotic enthusiasm and national pride, and also stimulate students' enterprising spirit in learning and stimulate their psychology to surge in a positive and healthy direction.

(2) Establish students' self-confidence.

Self-confidence is the cornerstone of success and a valuable psychological state, which can fully mobilize people's full potential, give play to their initiative and reach the best state. However, there are also differences in students' self-confidence, mainly in their studies and other activities. Such as: layered design exercises to meet the needs of different levels. In practice design, according to each student's different thinking level and jumping ability, different levels of homework requirements can be designed, so that students at all levels can answer some of them as much as possible.

(3) Exercise students' perseverance.

Setbacks are everywhere in life. It is impossible for a person to grow up smoothly, and it is inevitable that he will encounter all kinds of setbacks. Mentally healthy people will face setbacks with a positive attitude, adjust their emotions automatically in setbacks, overcome difficulties and work hard, and this kind of performance and perseverance to overcome difficulties will further promote the healthy development of psychology. People with poor psychological quality often panic in the face of setbacks, become negative and pessimistic, feel inferior and timid, hinder the confidence and motivation of progress, and have a negative impact on psychological development.

(D) to cultivate students' sense of competition.

In an ideal classroom, all students should be able to learn how to cooperate with others, compete for fun and happiness, and study independently. In the learning situation where competition and cooperation coexist, students' learning interest and ability grow together. Of course, the dominant position of cooperation must be emphasized here to ensure the healthy development of competition.

Thirdly, mental health education should be given to students in after-school counseling.

Teachers should design mathematical problems related to mental health education to cultivate students' healthy psychology. For example, when talking about "necessary and sufficient conditions", we can design the following questions: What are the conditions for getting into a key university with good academic performance? Through the discussion of this problem, students can understand the importance of healthy psychology to realize their ideals, and urge them to consciously abandon bad psychology in their usual study.

The process of solving mathematical problems is a logical reasoning process from conditions to conclusions. The relationship between conditions and conclusions is causal, especially in the analysis and proof, students need to think about what conditions a result has. Therefore, I think that by solving math problems, students can be educated to correctly attribute their test scores, learn to calmly and objectively analyze the reasons for the success or failure of the test, enhance their self-confidence and enterprising spirit in learning, and inspire their courage to work harder.

Fourth, pay attention to mental health education in teaching evaluation methods.

Many children who are tired of playing truant have been criticized and accused by many people in their study life, even satirized and sarcastic, and have serious psychological problems. Therefore, when evaluating students, teachers should pay attention to more encouragement, more praise, less criticism and less criticism, pay attention to the equality and fairness of education, try to find the bright spots of students, guide and cultivate them, and gradually cultivate their self-confidence and interest in learning.

5. Teachers' words and deeds will have a great influence on students' psychology, and teachers' words and deeds should be used to educate students' mental health.
